I am trying to load COA via ISetup. We are on 11.5.10.2. We have applied all the mandatory patches and at 11i.AZ.H.DELTA.2 level.
I got this link, AZR12LOADER Failed with An exception occurred in API 'Chart Of Accounts API' [ID 832383.1] on metalink for this error, to get the mentioned patches applied Patch 8445446 - Consolidated Patch for iSetup Fixes.

But this is for R12 instances, Do we have any alternative patch for this error's. Log file only show's this error. Dedug mode set to Y and @ 1.
